ABSTRACT:
A well water retrieval system for deep shaft wells including an electrical generator of limited generating capacity of the type that operates upon input of naturally occurring energy in wave or kinetic form as, for example, a photovoltaic generator. The system includes a plurality of electrically operated pumps each having an electrical energy demand not in excess of the generating capacity of the generator and a plurality of water reservoirs each sized to be disposed in a well shaft, there being a reservoir for most of the pumps. A conduit system supports the pumps and the reservoirs in a well shaft with the pumps and reservoirs stacked substantially vertically with the outlet of each pump connected to a reservoir higher in the stack and the inlet of each pump connected to an adjacent reservoir. A control is provided for operating the pumps selectively such that each pump drives water from its inlet to its associated higher reservoir to be elevated therefrom to another higher reservoir by another higher pump with the electrical energy demand of the operating pumps not exceeding the generating capacity. Consequently, a relatively small size generator may be utilized at a considerable cost saving.
